C++ pointers: why we need them, when we use them, how they differ from accessing to object itself

Even though most programmers understand what is the difference between objects and pointers to them, sometimes it is not entirely clear, which of the ways of accessing the object to choose. We have tried to answer this question below.

Programming Concepts: The Stack and the Heap

As we continue to use more advanced programming languages, we’re able to get some seriously powerful development done with much less code that does increasingly more awesome stuff, but that comes at a price. Since we don’t deal as often with low-level computation and processing anymore, it’s only normal that we don’t always have a full understanding about topics like what the stack is versus the heap, or how compilation really works, or what static vs dynamic typing is, or type introspection, or garbage collection, etc. Now I’m not saying every developer is ignorant of these, as most of us certainly aren’t, but I do feel like it’s worth revisiting some of the old-school important topics that we may miss out on these days.

The Ultimate List of Resources to Learn C and C++

The C programming language was originally developed for and implemented on the UNIX operating system by Dennis Ritchie. C, a quite simple language, is not tied to any particular hardware or system. This makes it easy for a user to write programs that will run without any changes on practically all machines.

Float or double?

Introduction

In scientific computation we use floating point numbers a lot. This article is a guide to picking the right floating point representation for you. In most programming languages there are two built-in precisions to pick from: 32-bit (single-precision) and 64-bit (double-precision). In the C family of languages these are known as float and double, and those are the names I will use in this article. There are other precisions: half, quad etc. I won’t cover these here, but a lot of the discussion makes sense for half vs float or double vs quad too. So to be clear: I will only talk about 32-bit and 64-bit IEEE 754 here. Continue reading
